Listen: Joanna Newsom and Feist Sing With the Muppets on New Soundtrack

As noted last month, Joanna Newsom and Feist are among the artists contributing to the soundtrack for the new film The Muppets. Check out the new "Muppet Show Theme", which features (barely-there) vocals from Newsom, at Stereogum. And hear quick vocal contributions from Feist and Mickey Rooney (along with the film's stars, Jason Segal and Amy Adams) on "Life's a Happy Song", below (via Bleeding Cool). "Life's a Happy Song" was written by Flight of the Conchords' Bret McKenzie, who served as music supervisor for the film.

Walt Disney Records will release the Muppets soundtrack on November 21, two days before the film opens in the U.S. on November 23.
